The Philadelphia Phillies are promoting pitcher Brian Keller to potentially start or serve as a bulk reliever on Saturday, marking his major league debut. Keller, 32, was originally a 39th-round draft pick by the Yankees in 2016 and spent six years in their organization before joining the Red Sox in 2022. He signed with the NPB Hanshin Tigers for the 2023 season but has pitched only 15.2 innings over three years due to Tommy John surgery and a subsequent nerve procedure.
